About
AgentMarketIndex is a catalogue of services that software agents call: data APIs, paid tools, MCP servers, x402 resources and agent-to-agent endpoints. It exists because an agent that needs to fetch a web page, price a token or transcribe audio currently has to guess which endpoint is real, what it costs and whether the price is current. Guessing is the failure mode we are trying to remove.
The catalogue is built from sources that publish their own records. Each entry keeps a link back to that record, the date we read it, and — separately — whatever we have measured ourselves. When we have not measured something, the page says so instead of filling the gap with a plausible number.
It is deliberately not a marketplace in the transactional sense. There is no checkout, no wallet, no escrow and no commission. Links go to the provider; you buy from them under their terms. That keeps the incentive simple: this site is only useful if the entries are accurate.
Corrections are the product
If an entry is wrong, the correction goes through the same form that new listings use, and lands in a moderation queue with the evidence you attach. Corrections are published with a status, not silently applied: a fix backed by a source is a provider claim, a fix without one is marked unverified. Either way the page shows which it is.
Who runs it
AgentMarketIndex is operated as part of the premarcu.com family of sites. Contact: ops@premarcu.com. Full provider details are in the terms.
No analytics vendor runs here, no advertising network, no fingerprinting. Server logs are kept for error diagnosis and abuse limits only.
